U NITED STATES i BFICEO CHARLES E. DODD, OF XVILLIAMSPORT, PENNSYLVANIA.

LETTER-COPYING MOISTENER.

SPECIFICATION forming part of Letters Patent No. 451,400, dated April28, 1891.

Application filed May 19 1890.

T0 coZZ whom it may concern;

Be it known that I, CHARLES E. DODD, of \Villiamsporuin the county ofLycoming and State of Pennsylvania, have invented certain new and usefulImprovements in Letter-Copying Moisteners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in letter-copyingmoisteners ordamping device, the object being to provide a convenient and efficaciousinstrument for retaining a supply of water and gradually emitting it aspressure is applied for the purpose of moistening the paper used incopying or transcribing written or printed matter; and it consists incertain novel features of construction and combinations of parts, aswill be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a plan view of my improvedmoistener. Fig. 2 is a transverse section, and Fig. 3 is a view inlongitudinal section.

A represents ahollow tube or cylinder composed of any hard substance,such as steel, copper, brass, or other metal or vulcanized rubber or itsequivalent. This tube or cylinder constitutes a roller adapted to berolled over the surface to be moistened instead of the moistening-brushin common use. This tube or cylinder is closed at its ends by theintegral and removable heads 1 and 2, respeotively. These heads aresubstantially alike, except that the removable head 2 is preferablyfurnished with a screw-threaded top 3, designed to screw intocorresponding threads 4:, formed in the open end of the tube orcylinder. The object of making the head 2 removable is to provide forsupplying the cylinder with water, which is poured in at this end, afterwhich the head 2 is screwed on again. The surface of the cylinder isprovided with numerous perforations, through which the water containedin it is discharged as fast as it is required in moistening the paper orblotters, as the case may be. The cyl inder is covered or faced withsponge, cloth,

felt, or other material, preferably of cylindrical form, capable ofreceiving, retaining, and, when pressure is applied, emitting moisture.The edges of the heads 1 and 2 project a distance beyond the surface ofthe cylinder about equal to the thickness of the absorbent material onthe cylinder for several reasons, prominent among which are to preventthe water from squeezing or oozing out at the ends, where it will beliable to get on the operator or on something else where it was notwanted, to retain the absorbent material on the surface of the roller,and otherwise give a neat finish to the article.

The removable head may be milled or otherwise constructed to facilitateits removal or application to the end of the cylinder, and both theheads may be furnished with handles extending out in line with the axisof the cylinder or at right angles to the axis, and one handle may beconstructed to receive water through it, or, still better, the handleshown in Figs. 1 and 3 may be employed. This is a spring-handle bentconveniently from a rod of metal into the handle proper'ti, formed by adoubling of the rod together, and in the spring-forks 7 7, whichterminate in the inwardly-projecting ears arranged to spring intosockets 8 8,

formed to receive them in the heads 1 and 2,

whereby bearings are effected at this point, so that the article may begrasped by the handle and the roller run over the surface of the paper.I

A device of this character is in constant domand, and it will supply aconstant deficiency hitherto felt and which the ordinary brush usuallyrelied upon in default of something better is not qualified to supply.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

As a new article of manufacture, a damping device consisting of a hollowperforated roller havingone removable head, the heads having socketstherein and annular peripheral flanges, a cylindrical absorbent materialadapted to receive and cover the cylindrical removable head and theflanges on theheads, specification in the presence of; two snbserihand aspring-handle having inwm-(iiy-pl'oing' Witnesses. jecting ears at itsends adapted to spring into the sockets in the heads to form bearings at5 the ends of the roller, substantially as set Witnesses:

In testimony whereof I have signed this V. E. HODGES.
